The PNG (Portable Network Graphics) format was created as an alternative to GIF, which at that time had a number of significant limitations. In particular, it is the need for a license to use that did not meet the requirements of the time. The PNG format has become completely open and patent-free.
Another significant difference is in technical specifications. First, PNG allowed the use of a significantly larger number of colors (up to 16.7 million in PNG-24). Secondly, support for full-fledged multi-level transparency with the use of so-called alpha channels. Hence the possibility of working with layers. All this led to the great popularity of the format among users.
